WILLIAM MoALLISTER, or LAWRENCE, MASSAOHUSETTSJD IMPROVEMENT INAPPARATUS FOR DY EING YARNS, &c.

Specification forming part of Letters Patent No. 153,973, dated August11, 1874 application filed June 10, 1874.

To all whom it may concern:

Be it known that I, WILLIAM MoALLIsrER, of Lawrence, of the county ofEssex and State of Massachusetts, have made a new and useful Improvementin Machinery or Apparatus for Dyeing Yarn; and do hereby declare thesame' to be fully described in'the following specification andrepresented in the accompanying drawings, of which- Figure 1 is a topview, Fig. 2 a side elevation, Fig. 3 an end view, Fig. 4 a longitudinalsection, and Fig. 5 a transverse section, of the dyeing apparatus ormechanism containing my invention. Fig. 6 is a top view of one of itsskein-holders.

The invention relates to the combination of a dye-vat and its groovedstandards with a rotary carrierrprovided with shelves, backstops, andconfining-chains, and having skeinholders, all being substantially ashereinafter explained.

In said drawings, A represents a dyevat, provided at its middle with twostandards, B B, which are grooved on their inner sides to receive andsupport the journals of the shaft 0 of the rotary carrier D, forsupporting the series of skein-holders. This carrier, as rep resented inthe drawings, is composed of three vertical parallel plates, a b 0,arranged at their centers upon the shaft 0, and at equal distancesapart, and fixed to said shaft. The said plates are connected at theirouter corners, as shown, by bars 11 d d d, and at their middles by twobars, 0 c, all arranged as represented. To the inner surface of thatpart of each plate which is on either side of the shaft, is fixed, asshown, a series of parallel narrow shelves, 8 8, there being the samenumber of shelves in one series as in its opposite or fellow series.Those of each series are arranged at equal distances apart. At their Iof skeins, g g, of yarn; it being run through each skein so as to holdit stretched or strained out.

Each frame or skein-holder, when prepared with skeins of yarn and placedwithin the carrier, will be supported on two of its shelves, in manneras represented in the drawings, the frames of each series being held inplace by the back rests or plates ff, and also by a chain, h, fastenedto the carrier-bars of the carrier, and extended down the middle of theouter ends of the series of yarn or skein holders. To the shaft of thecarrier, and against the outer face of one of its end plates, aspurgear, I, is fixed, to engage with a pinion, K, fastened upon a shortshaft, L. This shaft, supported in a suitable bearing fixed to the vat,is provided with a crank, M. On taking hold of the crank and revolvingit the pinion will be caused to revolve and turn the gear I, and therebythe carrier with its skein-holders will be revolved within the vat.

When the vat may be charged with a dyeing liquid, and the carrier is putin revolution therein, the several skeins will be alternately moved intoand out of the liquid. After they may have been sufficiently subjectedto the action of the liquid, the carrier should be raised upward in theguide standards and supported above the vat upon bars placed on its top,in order for the liquid to drain from the skeins. This having takenplace, the holding-chains should be unfastened, the severalskein-holders be removed from the carrier, and a fresh supply besubstituted.

The apparatus thus made is very useful or convenient for dyeing yarn inthe skein, and it may be used also for washing or scouring it.

I claim as my invention as followsthat 'is to say:

1. The rotary carrier D, constructed substantially as described, viz.,with shelves 8, two or more support-plates, a b c, shaft 0, andback-stops f, arranged and combined essentially in manner as specifiedand represented.

2. The rotary carrier D, provided with the shelves 8 and back-stops f,as described, and with a confining-chain, h, to each system of shelves,for supporting a series of skeinholders. 7

3. The skein-holder E, made and for use as described, viz. ofarectangular frame rounded -or with such and one or more series'ofyarnat the corners, and for use in themachine as holders, E, all beingarranged andto operate explained. substantially as set forth.

4. The combination of the dye-vat A and its WILLIAM MOALLISTER. groovedstandards B B with the rotary car- Witnesses: rier D, provided with theshelves 3, back-stops It. H. EDDY,
